1. AC input voltage setting
1. Input VIDEO signals and AUDIO signals to respective
terminals on the connector panel.
2. Set the slide induction transformer AC voltage as
shown in Table 2-3.
Model name Voltage
PVM-14L1 AC 100 V to 240 V ±10 %

2-6. Landing Adjustment (1)
1. CONTRAST... MAX
BRIGHT... Conspicuous position
2. Roughly adjust the white balance, G2, and convergence.
3. Switch the video signal generator output signal to
green only.
4. Move back the DY backward (in the direction toward
neck).
5. Adjust the purity knob so that the green will come to
the center of the screen. Make R and B almost
identical. (Fig. 2-1)
6. Switch to B only, R only, and G only and verify each.
7. Bring the deflection yoke gradually forward and adjust
the deflection yoke so that R and B on both sides of
the screen will be green. (Fig.2-2 → Fig. 2-3)
8. If the deflection yoke comes forward too much, the
pattern shown in Fig.2-4 will appear. If so, move the
deflection yoke backward. (Fig.2-4 → Fig.2-3)
9. Switch the signal generator output signal to the BLUE
only color and confirm the screen. (Fig. 2-6)
10. Switch the signal generator output signal to the RED
only color and confirm the screen. (Fig. 2-9)
11. When two colors are mixed, set the mixed color as the
standard, and repeat operations 6 and 7.
12. Switch to an all-white signal and check the uniformity.
13. When the deflection yoke position is determined,
fasten it with the DY screw.
